HIGH FIDELITY SOUND

FOCUSED ON SOUND QUALITY

SESSION 1

Electronics - Measurements and Objective Qualification

Instructors: Julian Fisher

Course Description:

What objective measurements can be made to qualify the performance of electronics used in car audio systems? Which measurements are most important in determining the performance characteristics of amplifiers and analog circuits used in digital products? What about DSPs and other digital devices? What design aspects contribute to audibly better performance and how do we confirm their value? 

SESSION 2

Speakers - Measurements and Objective Qualification

Instructor:  TBD

Course Description:

What do the graphs and the numbers really mean? Do they tell us how a speaker sounds? How are reliable and high-quality measurements of speakers made and what do they tell us? How the graphs, specifications and Thiele and Small parameters help us determine their intended use and help us extract optimum performance. 

SESSION 3

In-Vehicle Acoustics - Measurements and Objective Qualification

Instructor:  Andy Wehmeyer



Course Description:

What are the best ways to make in-car acoustic measurements and what do they tell us? Which measurements are most important, what equipment is required and how do we interpret them correctly? How can objective measurements of performance contribute to system optimization for current and future system designs? 

SESSION 4

The Relationship Between Objective Qualification and Subjective Analysis

Instructor:  Mark Eldrige 



Course Description:

Is it really “all subjective anyway?” What do real listeners prefer? Can objective measurements be correlated with subjective evaluation and listener preference? How understanding the correlation between objective analysis and listener preference and implementing what we know contributes to predictability in system design and performance.
